"I come from a civilised country..." Lucky you, Algol. Sadly, millions live in places you wouldn't consider civilised. And that forces some terribly difficult choices on them. But they're still choices. So you follow your precious moral compass. Your banker will be in a world of trouble, the girl will be deported to poverty, where she'll still be pressured to have sex with people she'd prefer not to, but you'll be bathed in the glow of the righteous.
